In the last year, the landscape of patent law was altered by court opinions from the Supreme Court and U.S. Court of Appeals for the Federal Circuit, as well as in opinions rendered by the Board of Patent Appeals and Interferences (hereafter BP AI) at the United States Patent and Trademark Office. In addition, patent reform legislation was introduced that could have shaken up patent practice even further. Although none of the reform proposals were passed, revised versions of these legislative initiatives have already been introduced in 2009. This brief write-up summarizes many (but by no means all) of the important developments in patent law in 2008 and early 2009.
